I hope they will work ok. Guess I will find out early next week! I will keep all posted

what size webers do people use again? Oh yeah, 40mm ones. 'cept with throttle bodys there isn't anything blocking the middle of them - air ain't gunna be a problem.

How about fuel, I've never looked into injectors on such a small NA motor, perhaps the extra base fuel pressure isn't a bad idea?

Yeah it's 600cc's but it revs to what... like 14K? Should be plenty of air. Fuel will be tuneable.

150 cc/ cylinder on the R6

I'd be interested to know the answer actually. There were a set of keihin carbs on ebay not long ago, very expensive though.


EDIT: I think Beattie and Sidedraught know a fair bit about m/cycle carbs on datsuns, it'd be interesting to hear what they have to say. I think it was Beattie?

i was thinking, r6 is .6 of a litre yes. your puttting this on a a12? will it be able to give enough fule/air ?

i thought r1 would of been the way to go

piccys as required


Just search ebay for throttle bodies.....most come from the states. but these are coming from melbourne.

Dattodude I think I know whats going on.

Retal Where did you buy the setup from? 100 squids is pretty damn cheap. I was trying to sus out what the setup looks like but couldn't find pics of it all. Post some pictures up.

Are the throttle bodies the newer revised 40mm ones or the old 38mm R6 ones?

yep listen to dattodude, except on my SR20DE with autronic setup We bumped the fuel pressure to 60psi for optimum spray pattern....best way is to have your injectors bench tested to see what would be the optimum pressure to run...

you want to regulate the 'pressure' between the pump and the injector. think about it after a beer, it makes more sense.

Sorry this may sound stupid but,

Why would the regulator go on the return?

I'm confusing myself the more I think about it.
